X5Jay, does your exhaust sounded like marbles in the pipes at higher RPM's after the X pipe mod??
Read the thread above to see what I´m talking about

How about long time reliability, can this X pipe deliver a proper exhaust back pressure, at very high RPM??? All of you that made the X pipe mod didn´t thougth about this question?
I am interested on doing this mod, but I´m afraid of ended like MrLabGui. He took out the X pipe and went back to stock resonaters.
Is the X pipe just a crossover pipe, if so, i think a good shop can make this X pipe fo less than 80 usd.
